Dribbled this into the Cherokee manifold, let it soak, and fired it up per the instructions. A cloud was produced that was visible from space. I would say it worked as advertised.

The trick, of course, is finding a good location to dribble it into the toofah manifold while its running. Maybe the throttle plate vacuum port?

I wouldn't put in your crankcase. . .it might wash away the crud that is actually sealing up the motor (crank seal, cam seal, valve seals, etc).

I chose the "pour it into the intake" method because I wanted to remove top end carbon buildup, and it seemed like using a concentrated dose direct to the problem area was the way to go. . .and i wasn't kidding about the cloud, it worked.

FWIW, Old school guys actually used water dribbled into the intake for the same purpose. . .

ive used it on a lot of my cars, buddys volvo, my infiniti, brothers galant vr4, and all of the cars had definate improvement with the stuff.

id definately wont help you pass inspection if theres still some in the system when u go to have her tested.

@rasta
Putting it the crank case and its affects on seals was one of my concerns as well.

I've heard about the smoke too and actually read an article on dripping distilled water in as well (somewhere on a Subaru forum). Its supposed to be like an internal steam cleaning - I've heard that works really well. But you gotta know what you're doing - lol.

@chicken
Thanks for confirming multiple uses/experiences. I am not counting on it to ensure the car passing inspection, I just want get the car cleaned out a little so it burns as clean as it should.

The car has got new exhaust - cat-back - so I'm pretty sure it will pass - I just like to make sure.


Plus, the whole smoke things has gotta be cool.

My car too has sat for a long time and want to try out the seafoam. When you say pour it in, and let it soak, where exactly am I pouring in to let it soak. It was said that in the crank case was bad. I have FI, so will i squirt it in the throtle body while it is running? Or is there a better or different way to use this product and get the best results. also, what is the best octane to use on a day to day? '78 NA. I have 93 in it now while i am getting it started, should I always use 93 or can I use a lesser octane?

I put about a third in my gas tank and now the car wont idle right. I was playing around with the carb a little so I need to spend a little time to get that adjust right.

But I, too, am a little confused where exactly to drip/pour this stuff in. The instructions say to do it while the engine is running, shut it off for 5 minutes, then start it up and run until the smoke clears. But there is no way I see possible to access the carb while the car is running - without choking it to a stall.

Should I remove carb intake hose and pour it in there - start it up and keep it running as long as I can, let it stall out and start it after 5 minutes?

Just a little confused as to how to inject/pour this stuff into my 79 NA.

Carb? What kind of carb do you have? (I've only heard of multiple carbs, made either by Weber or Dellorto, being fit to a 924.) -Anywho... normally with a carb, you'd remove the air cleaner/s and slowly dribble the liquid directly into the carb/s.

With the factory CIS fuel injection setup, you'd have to arrange for it to be sucked in through an intake manifold vacuum port. Probably use a T to add a couple foot length of line, T'ed in with an existing vac line, and hold the other end of it right at the top surface of the liquid (in a clear container* so you can see where it's at), and let the vacuum slurp it in slowly a little bit at a time...


*- Some plastics might crack or melt depending on the type of fluid used, so use a glass container.

Seafoam is a good product. I have used it mainly in crankcase applications, but have run it through the gas a couple of times in various vehicles. It will definitely remove deposits.

You may need to finish that tank of gas out, and put in fresh gas to pass your emmisions, though. While in the auto business, I needed to get many cars through emmisions tests, and sometimes the additives we used to clean out the fuel system caused them to fail. Fresh gas and a retest usually worked. As an aside, on engines that were starting to use a little oil, switching from dino to synth oil would help them pass. We saw this time and again.

A personal seafoam success story: I put seafoam in the crankcase of the '82 931, because my turbo had gone inop. Stuck, wouldn't spin. I have never replaced the turbo, so I thought that after 20 years of ownership, I was due. I was bummed though, because I religiously idle cool the turbo before shutting down, and had always used synth oil. But after checking everything out, there was no denying that turbo wasn't spinning.

I went ahead and purchased a rebuilt turbo from a board member, but just before tearing everything apart, put the seafoam in to see what would happen. I drove the car a few times over a couple of days (what a dog it was with a stuck turbo), and all of a sudden, the turbo freed itself. It is has been operating flawlessly ever since. I still haven't replaced the turbo.

As a footnote, I had used an oil additive shortly before the turbo froze, that was supposed to be synth compatible, and I think that is what coked up and caused the turbo to stop working.

Good luck! Cheers, Brian

In other vehicles, I've pulled the brake booster hose, attach, turn the can over, and it sucks it up quite quickly!
